Here’s an idea: brew some masala chai, just the way you like it. On youtube there are wonderful videos showing how to make it the traditional Indian way, on the stovetop with milk and spices such as cardamom. Once you have your pot or cup of chai, chill it in the fridge. Next, use a blender and combine your chilled chai with some ice or some vanilla ice cream or pieces of frozen banana. I’ve also had it with chilled cashew milk.
